Application September 19, 1949, Serial No. 116,549

1 Claim.

This invention relates to a dual tap T for bath-tubs set back to back.

An object of this invention is the provision of a dual type fitting for a perfect job of connecting back for back bath-tubs with the plumbmg.

Another object of the invention is to provide a dual tap T especially adapted only for bathtubs in duplex apartments and hotels.

A still further object of the invention is to provide a special device wherein the horizontal inlets are formed in the nose or hub thereof and said inlets being exactly twenty degrees ofi center.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a diagram showing portions of two bath rooms with the bath-tubs therein set back to back and showing within the wall the improved dual tap T, in accordance with this invention.

Figure 2 is a view in elevation of plumbing including devices constructed in accordance with the present invention.

Figure 3 is a front view in elevation of a dual tap T in accordance with this invention, while Figure 4 is a vertical, central sectional view of the same.

Figure 5 is a top plan view.

Figure 6 is a horizontal, sectional view taken on line 6-6, Figure 3, and looking in the direction of the arrows.

Referring to the drawings, in which the preferred embodiment of my invention is illustrated, I, l designated two bath rooms, which are separated by the wall 2. In each bath room I is what is known as a built-in bath-tub 3. The two tubs 3 are set end to end and the novel dual tap T constructed in accordance with this invention is placed within the wall 2.

The dual tap T comprises a long section 4 and a short section 5, integrally connected together. On the upper end of sections 4 and 5 is a double caulking hub 6, which usually is positioned above the floor I in each instance, to avoid unnecessary cutting of timbers, which speeds up the work and makes it easy to caulk the lead joints.

The lower or inner end of the short section 5 is thickened (Figs. 4 and 6), producing a hub or nose 8 that extends outwardly. In this hub or nose 8 are formed two horizontal inlets 9; these inlets 9 are 20 degrees off center for efficiently accommodating the two traps III for the end to end bath-tubs 3. The inner wall of the short section 5 is curved at ll, Fig. 4, to allow free flowing of the waste fluid into the waste passage I2 of the long section 4. The vent passage |3 of the short section 5 is in communication with the vent pipe M, Fig. 2. The waste passage I2 of the long section 4 is in communication with the waste pipe l5, Fig. 2.

It is to be understood that the device herein described is peculiarly constructed for use in the plumbing only of bath-tubs, arranged end to end, which peculiar positioning of bath-tubs is usually found in duplex apartments and hotels. Further, the peculiar construction of the hub or nose 8, with its two horizontal inlets arranged 20 degrees on center, makes this device highly efficient for the special plumbing, or hereinbefore described.

This device can be easily positioned within the wall, with no projection showing in a room, and by reason of its structure, unnecessary cutting of timber is eliminated, as well as speeding up the work, both in positioning and the caulking of the joint or joints.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claim.

What I claim is:

In a soil pipe fitting, a sanitary member having a relatively long section and a relatively short section extending for the greater part of its length parallel to the long section, said short section being of a length substantially one-half of the long section and merging into the long section intermediate its ends by a reverse curve, the curved portion of the short section having a thickened portion forming a nose projecting away from the long section with its vertical median plane coinciding with the plane of the axes of said sections, said nose having a pair of openings leading from the surface of the nose to the interior of the said bend,. the axes of said openings radiating from the axis of the short section at equal acute angles from the plane of the axes of the sections.
